I played some more with fmit: it has a setting to detect quieter notes,
but the rest of this email applies with a vengence when detecting these
quieter instruments - fmit has no concept of the attack of a note - not
onset detection that aubio provides - it splurges out a large battery of
random junk every time you pluck a string. Denemo on the other hand
detects what the note is and smoothly follows the pitch thereafter.
